[0025] In this embodiment, when processing the wrist-arm tube, the wrist-arm tube is first placed on a supporting device, and the tail of the wrist-arm tube is placed on a traction device 4, the tail of the wrist-arm tube is fixed by the traction device 4, and then the wrist-arm tube is driven to move left and right to a suitable position so that the wrist-arm tube is in a target cutting position, and then the wrist-arm tube is pressed and fixed by a pressing device, and finally the wrist-arm tube is cut by a cutting device 5.

[0026] Further, see Figure 2 As shown, the supporting device includes a plurality of supporting wheels 31 arranged laterally and spaced apart on the operating platform 2, the cross section of the supporting wheel 31 is V-shaped, and the supporting wheel 31 is mounted on a supporting wheel mounting frame and can rotate around its own axis.

[0027] In this embodiment, a supporting wheel 31 with a V-shaped cross-section and capable of rotating around its own axis is used to support the wrist-arm tube. This can not only provide good positioning and support for the wrist-arm tube, but also enable rolling friction between the wrist-arm tube and the supporting device when the wrist-arm tube moves, thereby reducing friction, reducing wear on parts and saving energy.

[0028] Furthermore, the clamping device is installed on the rear side of the supporting device, and the clamping device includes a gas-liquid booster cylinder I32, which is installed on the upper end of the cylinder support frame with the output end facing downward, and a pressure block 33 is installed at the bottom end of the output end of the gas-liquid booster cylinder I32, and the pressure block 33 matches the wrist arm tube placed on the supporting device.
